[svn-r20384] Purpose:
Fixed Bug 2184 - GMQS: h5diff - incorrect calculation code for
--use-system-epsilon option
Description:
Merged from HDF5 1.8 branch r20369.
Fixed h5diff for --use-system-epsilon option: the calculation changed
from ( |a - b| / b ) to ( |a - b| ). This was decided for better
performance and was corrected only in HDF5 trunk, so 1.8 got updated.
Also comments for equal_XXX() function were updated correctly.
Also help page and RM got updated correctly.
Also add test cases for testing the differences w/wo the option.
Tested:
jam (linux32-LE), amani (linux64-LE), heiwa (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE), Windows (32-LE)
